WATER-HEATER.

Specification of Letters Patent.

Application filed February 2, 1915., Serial No. 5,738.

I 3e it known that I, FREDERICK POOLE, a citizen of the United States, residing at Jewell, 1n the county of Jewell and State of Kansas, have invented certain new and useful Improvements in Tater-Heaters, of which the following is a specification.

This invention relates to water heaters,

pipe line and an electric heating` element is. carried within the casing and spaced from the walls'ther'eof, the water or the like flow'- ing'through the casing around the heating element thereby instantaneously heating the water.

'Another object, of `my invention resides -in the provision of suitable i eans for support-ing the heating element ing mentioned.

A still further object ot' my invention rewithin the cassides in the peculiar manner in which the heating yelement is disposed in the pipe line, aA plurality ofl branches being associated with a main source of supply, and a heating element being associated with one of the branches.

IVith the above and other objects in view,

my-invention resides preferablyin the conf struction, combination, and arrangement'ot parts as hereinafter set 4forth in the specilication and illustrated,l in the accompanying drawings, in which-. 4

Figure 1 is a topplan view of a -m'ain source of supply and two branches illus- 4trating one application of my invention.`

Fig. 2 is a longitudinal sectional view of one form of my invention. y

Fig. 3 is a det-ail view of a spacing element which I utilize in the preferred' embodiment of my invention.

Similar reference characters indicate similar parts throughout the various views of the drawings.

Referring more particularly to the drawingsA` in Fig. 1 I have illustrated one of the many applications of my invention, and in this instance the form illustrated in F1g.`2

has been shown in elevation. It will be noted that I have illustrated a source of liquid supply 1v having two branches or tributaries 2 and 3, the said tributaries 2 and 3 terminating in outlet faucets l and 5 respectively, of any approved design. rlhe water heater is `indicated generally by the 4numeral G, vand it will be noted that the water heater `G is interposed in the branch 2 between, the source et supply landthe outlet faucet 4f. An auxiliary valve Z is provided to shut oli' the liquid supply in the branch 2 when it is desired lto repair or clean the water heater 6. A' suitable source of electric current supply is indicated. by the numeral S controllablehy'the switch 9, electric conductors 1i se?A `Ying to supply electric current to the heater. An electric connecting plug-of anysuitable' design may beemployed .tor 'the purpose of alt'ording detachable electrical communication with the resistance coil 25, but I prefer to use a form which I have illustrated, andindin I cated generally in the .accompanying draw-A ings by the numeral 10.

From the above description, it will be seen 'that the water heater' is so disposed within one of .the branches provided so that liquid yflowing therethrough will be instantly heated, and `it will benoted that the source of suI-plyl 1 may reside in only one water or liq iid conduit until 'the point at which the hot water may. be desired is reached, at whicl' point a branchzor branches may be provilled in. the conduit 1 and my improved heater applied thereto.

I,have illustrated a present orni of my improved heater in Fig. 2, and in this View,

it willbenoted that I provide a casing 11 havinO' end ca )s 12 and '13 which are iny s l i threaded engagement with the casing 11 as indicated at 14e and 15, re pectively, the said screwcaps 12 and 13 beingprovided with central alining threaded openings -16 and 17, respectively, into which may be threaded the ends of water -conduits 18 and 19, re-

spectively, the said' water conduits 18 and i The casingA 2() and cap 22 are preferably element.

linea 'with Some insulating ,material indicated at 24, and a. coiled resistance element -or the like is "receivablewithin lthe casing 20, the insulating material 24 being interposed between the resistanceelement 25 and -the Walls of thecasing 20 so as to insulate the same therefrom for an obvious reason. Ihave diagrammatically indicatedv the heatlng element and lit will be understoodth'at any .of the many advantageous forms of heatingelements may be utilized whenv desired, and that I do not desire'to be limited to vany' particular form of yheating The casing'QO- is spaced from the inner surface l.of the casing l1 by means of a spacing band the said spacing band having a plurality of 'radially extending projections 31 thereon', being divided as show-n at f3@ and having a clamping screw ypassing therethrough in order to retain the same iny lengagement with the casing 20, the said radial extensions 81 engaging the inner s urface of the casing 11 yand spacing tlie'said heating element therefrom.v y I desire t'o lay stress upon one of the very,"

advantageous features of my invention whichl is that thesame maybe interposed in a tributary of a-main source of supply a second tributary beingdisposed adjacent' the same, so that-hot and cold Water may be readily had vWithout the use of compli'-, cated heating devices.` It ispreferable to. lconstruct fthe'casing 20 of some non-corio. sive material andl care should also be taken vthat ythe material used. is Aone which has yahigh heat conductive coeflicient,-so that the transmission of heat from the heating coil contained therein will be practically instan-' taneous.

A threaded bushing 26 provided sup-V` porting the casing 2O 'in spaced relation t0. the casing 1l, and a Washer 27 arranged' rupon thel bushing assists in this function, the electric'conductors 28 passing'through the bushing 26. o

,The applications of my invention which I'have illustrated in the drawings are only a few of its many applications,`and While I have shown and' described the same as possessing a peculiar vform and construction,

' it is desired that I may make such changes -in the detail structure thereof as do not depart from the spirit and scope of the in vention as'claimed.

` What isl claimed is':

l. A Water heater including a casing interposed in a pipe l1ne,.a .second caslng fivithin said-irst casinghaving a removable closurel cap, an insulating lining for the sec- Y ond casing and the closure cap, an electrical heating element insaid' second casing, a connecting plug carried by the main casing and connected 'to-said heating element, a.

spacing element formed of heat non-con.

ducting material arranged adjacent the connecting plug', and a band arranged about the second casing for maintaining the same in spaced relation fromsaid rst casing.

- In testimony whereof I affix my signature in presence ot two Witnesses.
